IMPROVEMENT IN LAMP-BURNERSA Specification forming part of LettersPatent No. 92,945, dated July 10, 1877; application filed February 5,1877.

To all whom it may concern Be it known that I, WILLIAM SILvEsTER,

of Pittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented certain new and useful Improvements in Lamp-Buruers and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawing, formingpart of this specification, and of which- A Figure 1 represents a frontelevation. Fig. 2 is a horizontal section taken at the line as w of Fig.1; and Figs. 3, 4, and 5 represent details.

In the use of oil-lamps it occurs frequently that the wick-adjustingdevice becomes defective and fails to do its work. The cause of such adefect might be the bending of the stem upon which the adjusting-wheelsare fixed, or the Wheels might become loose on the stem, &c., and, asthe pieces cannot be taken out Without destroying the wick-tube itself,the lamp will be unfit for further use.

The object of my invention is to construct the wick-tube in such amanner that it will be repairable at a very slight cost.

For this purpose I provide the wick-tube A,

opening 0. The end of the stem 8 is lodgedj in a circular hole of thetube, while the rear of the stem is supported in a slot. By this meansthe adjusting device can be taken out of the wick-tube, and might, ifnecessary, be replaced by a new one, and without the loss of other partsof the burner. The opening 0 is closed by a little door, d, which alsokeeps the rear of the stem 8 in its place. In Figs. 1 and 2 the door isrepresented as being open. Having thus described my invention, what Iclaim as new is- 1. In a lamp-burner, the Wick-tube having an openingwhereby the adjusting device can be taken out, as described and setforth.

2. The wick-tube A, having opening 0 and door d, as described, and forthe purpose set forth.

WILLIAM SILVESTER.
